Quickly packaging services using Nix flakes (Part 1)

Guides
1

I’m writing a small guide on how to package software and services for yourself as flakes. Part one is out now here: Part 1: Quickly packaging services using Nix flakes

Somehow I really struggled with this after I first setup my nixos system as a flake. I’m also still fairly new to this, so any feedback and pointing out of the mistakes I made is appreciated!

Part 2 will hopefully come next week and I will then update this thread.

I finally (after only 6 months) managed to write the second part!

In part 1, you’re using the anti-pattern of import nixpkgs. Maybe update it to pkgs = nixpkgs.legacyPackages.${system}. See also: 1000 instances of nixpkgs

You may also want to link to the second part from part 1. Right now it looks like it’s just not finished.

The update wasn’t quite right. You changed it to pkgs = pkgs = nixpkgs.legacyPackages.${system};, the first pkgs = should be removed. I also just noticed it’s in part 2 as well, but in a different location:

nixpkgsFor = forAllSystems (system: import nixpkgs { inherit system; });

should be

nixpkgsFor = forAllSystems (system: nixpkgs.legacyPackages.${system});

but thank you for the quick corrections!
